Today I stripped the power coating off my Oil Bud oil cooler.  The power coating was easily removed with aircraft remover.  It will be going to Swain Tech to get their BBE heat radiating coating to help take some addition heat out of the motor.

Also, after talking with Scott we decided up up the compression to 11.2:1 to get every last bit out of this build.  In addition, I decided to add a little gearing and ordered an Evolution Industries 49 tooth billet clutch basket.  With this addition, I'm sure there is no way I won't be happy with the performance of this build.

All my parts came back from Hillside week before last.  Scott said the heads ended up flowing 315 cfm with the Swain Tech flow coat in the intake.  He said it picked up around 6 cfm vs. the uncoated ports.

I finally cleared my weekend to start the assembly, and ran into some snags.  The gasket that was used to mask the cylinder head was for a 4.125" bore bike as the OD of the ceramic coating measured 4.155".  The heads went back to Hillside to re-mill them to remove the ceramic coating from gasket and quench area.

I did remove the original cam bearing and installed the new bearings.  The eBay puller/installer I purchased worked okay once I modified the collet.  I had to cut the slots in the collet about 3/8" deeper so it would flex properly.  After that, it worked okay for the once in a blue moon installs that I will do.  I also used the lifter block alignment studs for Evo's to align the oil pump before I tightened the nuts down.

The Zippers dual piston chain tensioners were used to button up the cam install.

Below is the S&S 58mm Throttle Hog throttle body compared with the stock 50mm.  It was designed for use with 1.800" intake ports as well.  The biggest advantage I see is that the S&S has a much bigger intake plentum volume and the volume comes from the bottom of the intake.  With ports shaped like the Harley's, the most flow potential will come from the bottom of the intake.  Nicely done S&S!!!

wow this is really good stuff here .... I have a ques what are the benefits of the ceramic coating of the heads besides better flow.
does it reduce carbon build up ?

also the difference of the 6cfm  air flow  is  that a lot where you can tell on the butt dyno ?

again thanks for posting the pics and info

Ceramic coatings are not for better flow.  They are for insulation.  I'm trying to keep the heat in the combustion chamber, out of the piston, out of the exhaust port, out of the head, and ultimately out of the oil.  I did have the intake ports coated in a product called flow coat.  It is a very slick coating that was designed to improve flow.  I also had my pistons coated with the 'Gold Coat' on the top and my oil cooler coated with a heat emitting coating.  Bottom line, the coating should help manage heat and I feel this is critical in a air cooled motor.

Below are pictures of my pistons with Swain Tech ceramic Gold Thermal Barrier Coat.

IMO if you bust through 130 on an honest dyno you have a winner. I have seen similar builds go there with no coatings and lesser TB.

True.  Plus I'm not going to get hung up on dyno numbers because there are no two dynos that read the same.  That's a goal because it would be cool to brag, but ultimately it's all about how it rips when the throttle gets twisted!   :2vrolijk_21:

My Oil Bud oil cooler cam back from Swain Tech with their Black Body Emitting coating.  It's very thin almost like an anodizing and it has a semi-gloss appearance.  I easily see how it is better than a thick power coating.

The heads made it back this week.  I spent all day yesterday double checking all measurements.  Since I knew the ACR's only open .020", I removed the additional shim that was added to ensure the chambers would be as small as possible.  I cc'd the heads (about 5 times) and was disappointed in what I found.  The front head is 94.5cc's and the rear head is at 94cc's.  I asked to the heads to be at 93cc's for the 11.0:1 and Scott said he would bump that to 11.2:1, so I was expecting to find sub 93cc chambers.  Just to make sure I wasn't missing anything, I went back and made a mold of the piston crown.  I cut off the valve reliefs and cc'd the mold.  I cc'd the reliefs on the piston and subtracted the two.  Again, I found my self disappointed as the total cc's on the piston dome volume as they were only 10.5 cc's instead of the 11.5 that I read on the board.  After that, I checked my deck height of the pistons.  I found the rear sitting in the hole .0065" and the front in the hole .0035".  The top of the piston above the ring land measured 3.968" and it was .172" to the top of the ring land.  Lastly, my .027" Cometic gasket had a bore of 4.034".  When you factor all that together, my compression is as follows:

Front Cylinder Static - 10.91:1
Front Cylinder Dynamic - 9.45:1 (calculated @ .053" lift....so not true dynamic compression)
Rear Cylinder Static - 10.89:1
Rear Cylinder Dynamic - 9.44:1 (calculated @ .053" lift....so not true dynamic compression)

I was wanting the compression up there at 11.2:1 (about 9.65-9.7 dynamic compression), so now I'm left with a decision.  I can throw everything together, have the heads milled more to get the chambers where they need to be, or buy a -4 degree cam gear to get my dynamic compression back to the 9.65:1 that I had planned the build for.


Does anyone have any thoughts or suggestions on which direction they would recommend?

Consider shaving the front barrel .003 and the front head .009 rear head .003, YMMV to get the heads to match at 93cc.
After all the detailed work you have done no sense in shortcuts. You will be at ~11.15:1 after the work is completed.

I know you're right...I was just hoping that someone would tell me that the -4 cam gear wouldn't affect the power that much.

So, I think the plan is to take off .010" off the rear cylinder and .007" off the front cylinder.  That will put the slugs .0035" above the deck surface and put the quench at .0235" when cold. I'm guessing that will translate to somewhere around .035" quench when warm.   I'll also have the heads milled (again...time #3) and chambers set to 93.5cc.  Based on my calcs, that will put the compression at 11.18:1. 

Now, just to try and find a good local machine shop that I trust....

Several things...........
I've cc'd many sets of 110" domed pistons like you show in your pics. They ALL have come in at 11 cc.
Also, if you're checking your deck height beyond the valve pocket area(your bottom pic), there's more room for error  :oops: than over each end of the wrist pin.
